Yama Sakura is a simulation of the defense of Japan in which participants practice the skills and requirements needed to deploy to aid with security of the region. Personnel from multiple sections, including intelligence, current and future operations, logistics, medical and legal, are engaged in the exercise.

The annual exercise moves to a different location in Japan each year, allowing the U.S. to work with each of Japan's five regional Armies.
